The pregnant teenager who fatally shot her boyfriend in a YouTube prank gone horribly wrong pleaded with a 911 dispatcher to send help as she watched the father of her children die of a gunshot wound.

As CrimeOnline previously reported, Monalisa Perez, 19, accidentally shot and killed her boyfriend, 22-year-old Pedro Pedro Ruiz III, outside their Minnesota home last month. Monalisa and Pedro were aspiring YouTube stars who frequently recorded videos of stunts and pranks. Pedro had reportedly convinced Monalisa to record a video of her shooting him with a book held up to his chest — believing that the book would stop the bullet.

It didn’t, and the bullet pierced Ruiz’s chest, killing him. Perez has been charged with second-degree manslaughter.

The Star Tribune obtained a transcript of the frantic 911 call Perez made on June 26, from inside her home as Ruiz lay mortally wounded outside. According to the transcript, Perez said had to call from inside the house because the battery on her cell phone was dying and she needed to plug it in.

“We were doing a YouTube video, and it went wrong,” Perez said to the dispatcher, according to the transcript. “Please hurry up. … My God, hurry up, please!”

At one point, the dispatcher tells Perez to go outside and check on Ruiz.

Perez also mentioned in the 911 call that she was nervous about the stunt, as she said in her last Twitter post before the tragic accident.

“Oh my god, I knew,” she reportedly said to the dispatcher.

She also told the dispatcher that the incident was recorded.

The Star Tribune reports that police have obtained video recording of the shooting, but that they do not plan to release it. Police told the newspaper that Ruiz held a hardcover encyclopedia up to his chest, and Perez fired a .50-caliber Desert Eagle pistol from about a foot away.

As CrimeOnline previously reported, Perez told police that Ruiz told her he had practiced the stunt on a book before, and that the bullet did not go through the book when he tried it.

The couple’s three-year-old daughter was present at the time of the fatal shooting, and Perez is pregnant with their second child.

Perez was reportedly released on conditional bail that requires her to wear a GPS monitor and prohibits her from accessing firearms.
